In suitable spaced apart bearing framework posts or standards 1, 2 a stout shaft 3 is fixed having journaled on a projectingwhich is supported Wholly by saidshaitt and withits outer'extremity tapered off as indicatedat 5 to athin edge .6; .The mandrel 4 end thereof a long cylindrical mandrel 4 is constantly rotated in any suitable manner as by a sprocket and chain connection 7 from a prime drive shaft 8 mounted in suitableequipped with usual driving pulleys 10. .A paper web is supplied for winding drel 4andj as shown constituting part of a pitch coating station where the outer sur-' 9 and shown as face of the paper as it is wound on the mandrel is previously coated with pitch from a pitch applying roll 12 which receives hot pitch from a pitch roll 13 ina heated pitch tank 1 1 as is usual. The disposition of the coating station and roll 11 with respect to s the mandrel 4 is preferably such that the spiral winding overlaps to some httle extent as indicated at O. For supplying a seriesof spaced apart-threads or filaments to extend lengthwise of the tube as it is formed,

I provide a carrier 15 mounted for rotation in a ring bearing 16 which encircles said carrier. The carrier 15'is preferably and as ments to be spaced as closely together as may be desire Connections are provided for rotating the spool carrier 15 in the same direction as the mandrel 4 and preferably atthe samerate of speed so that the threads as given out therefrom will extend straight lengthwise of the mandrel. For this purpose the prime drive shaft 8 is connected to drive a countershaft 17 mounted adjacent thereto and in parallelism therewith through spur gearing 18 with an interposed intermediate gear 18 so that the shaft 17 is turned in the same direction as the shaft 8 and at a 'considerabl higher rate of speed, the larger gear 0 the gear train 18 being fixed on the shaft 8. The shaft 17 through spur gearing 19 including an intermediate gear 19 engages a ring gear20 on the carrier 15 to rotate the same, the described gear connections including the sprocket drive 7 being so proportioned that the carrier 15 will thus be turned at the same rate as the mandrel. The carrier 15 has fixed thereto a guide ring 21 equipped with a series of spaced apart passages through which the threads are guided and given out from the respective spools, this guide ringencirclirig and lying relatively close to the periphery of the mandrel 4 so that the threads are thus held to be laid in parallelism and straight lengthwise of the mandrel onto the paper tube as it is drawn lengthwise off the mandrel as presentl described. In advance of the carrier 15 mount for rotation a second spool carrier 22 in a ring bearing mounting 23. This carrier is equipped with a ring gear 24 with which meshes a relatively large gear 25' fixed on the shaft 17 whereby the carrier '22 is driven in a direction opposite, to the direction of rotation of the mandreland of the I carrier 15 and'at a relatively high rate of speed. This carrier is equipped with a plu-- rality of spools S which'may be varied in num er according to the spacing ldesired of.

spools S the threads are led through passages of a guide ring 26; fixed to the carrier directions of the mandrel 4 and the carrier 22. with respect 'to each other. I preferably apply to the paper tube thus constispirall For this purpose a second paper web is delivered from a suitable source of supply arranged diagonally with respect to the mandrel this being shown'as a second ic'oating station 27 similar to the station 11 but which is arranged to coat the under surface of the paper web as it is Wound on to the mandrel. For operating the rolls of the coating stationsll, 271 show connections from the prime drive shaft 8 consisting in bevel gearing 28 driving a transversely extending flexible shaft 29, the other end of which is connected by bevel gearing 30 to the operative rolls at the station 27 while a sprocket and chain connection 31 leads therefrom to a shaft extension 32 from the rolls of the coating station 11. The-delivery end 5 of the mandrel is formed to. change gradually from a cylindrical cross section to the extended edge extremity 6 in a man-.

ner so that the perimeter thereof remains substantially constant and hence the completed tube as it is drawn off the mandrel will .tuted'another layer of paper also wound be changed from a circular section to a flat tened out one without wrinkling or'mutilation. In accordance with my invention means is provided adjacent the mandrel ex= tremityfi to draw the tube constantly off the mandrel ata rate proportional to the production thereof by the described spiral Wind'- ing. For this purpose a rotating frame work 33 is provided, mounted to turn in spaced apart ring bearings 34 and equipped with a ring gear 35 which is engaged.

through an intermediate with a gear 36 fixed on the end of the shaft 8, these gear elements being so proportionedthat the frame 33 will be rotated in precise unison with the mandrel. The outer one of the stationary bearing mountings 34. has fixed thereto an internal ring gear 37 with which meshes constantly a gear 38fixed at. the end of a shaft 39 journaled lengthwise of and adjaorbital the statlonary ring gear 37 so that it and the shaft 39 will be driven thereby as the frame 33 rotates. the transversevthreads that'are wound to' encircle the tube as it is formed. From the 'front end of the frame 33 so that the receivmgmouth between said rolls is diametrical cent one side of the frame 33 whereby the.

gear 38 carried thereby will describe an ath andalways keep in mesh with of the frame 33 and in line with the delivery edge 6 of the mandrel. I preferably provi e .means whereby these rolls, which receive between them and press'the. flattened tube, are ad'ustable toward and from each roll of completed tube on the mandrel 45' other accor ing to varying thicknesses of stock which may be handled to produce the the frame 33 and acted on by a compression slida roll of tube thereon increases in diameter,

tube. For this purpose the shafts 41" of these rolls are mounted in bearing blocks 41 slidably mounted in a housing 33 of coil spring 43 which normally tendsto press said bearing blocks apart. One of these bearing blocks is acted on' from' itsouter side by an ad'u'stable wedge member 44the adjustment 0 Y which by a nut 44 thereon acts to press the rolls toward each other to a predetermined extent, it'bein of course understood that such adjustab e mounting is employed at each end of this pair of rolls.

A. take-onmandrel 45 for the completed mounted between a tube T is detachabl driving, arbor 46 an a tailstock arbor 46 transversely central and diametrical of the frame 33. This mandrel is driven'by means of a friction disk 47 rigid with the arbor 46,-

this disk having an-outer friction face which is engaged by an adjustable friction disk 48 'ly keyed on a shaft 49. The shaft 49 is journaled atits ends in bracket members 50, 51 journaled -to swing on the shaft 39 and it has fixed at one end thereof a ear 52 which is driven by a pinion 53 fixe on the shaft 39. -The friction disk 48 is held pressed against the face of the disk 47 by tension springs 48'. anchored -to the frame 33 and engaged with-the outer end of the brackets 50, 51/ Thus the take-on mandrel 45 will be driven at a rate determined by the radial distance of, the driving' friction disks 48 from the driven disk 47. Since it is requisitethat the take-on mandrel be rotated at a progressively lower rate as the means is provided whereby the friction .disk 48 is shifted automatically gradually outward with respect tothe axis of disk 47 .in

- the operation'of the machine. For this pur- {pose the disk 48 hasa grooved neck 49" en .50

gaged by a shipper bracket 54 having a nut portion 54? engaged by a threaded shaft 55 which is journaled at its ends in the'bearing brackets 50, 51. The shaft 55 has fixed to a series of this a feature of value and im ortance since in the use .of pa er relnforce 'tation o'f'the frame 33 and to an extent so that the peripheral s eed of the roll as it is built up on the-man rel 45 will be substan tially constant. Since forthe different characters and thicknesses ofthe tube stock, the

will build up with varying degrees of rapidity, I provide means whereby the rate of radial movement of the disk 48 with respect to the disk '47 maybe varied as required.

For thispurpose an adjustable guard meme ber 59 is provided and secured to the bracket 50 adjacent the ratchet wheel 56 by a bolt and slot clamp 59. The pawl 57 is equip ed with a .roll. 60 near its outer end adapted to engage on the guard member 59 and lift the pawl 57 out of engagement with the ratchet wheel 56 after a predetermined ex- 'tent of actuation thereof. Thus by shifting 'the' ard member 59 the pawl is caused'to actuate the ratchet wheel to agreater or less extent at each operative movement and'thus varythefeed impulse imparted to the disk 48 according to requirements.

In accordance with my invention the'periphery of the mandrel 4 isreferably serrated or ribbed lengthwise t ereof as indicated at 4, presenting thus a spaced apart 'arallel edges around which the paper an threads are successively wound. This contributes to the ease and readiness with which the aper tube is drawn endwis'e alon prematurebreaking stresses by the full reinforcing action of the filaments. I consider by yarns or the .man rel, by reason of reduced. .fI'lCtlOIlfil area and it is also a feature of filaments. hereto ore it has been difficult to.

tension the threads relatively with respect to the paper 'sothat the'threads would hear their proper share'of resistance to stresses, it being initial y taut would break before any "considerable. part ofthe stress was taken up projecting end thereof a ratchet wheel'5fi/by the reinforcing filaments. The operation equipped with a handle 56 for manual operation when'desired; This ratchet wheel which is thuscarried eccentrically of the frame 33 is engaged at every rotation of the frame 33 by'a pawl .57 acted onby a spring 57 pi'voted to a bracket 58 secured to abar of the mechanism will be readily understood without further detail description. .The described gearing carried by the rotating frame 33 is so proportioned as to turn the rolls '41 and'thetake-on mandrel 45 at just the correct rate to draw "the com leted tube continuously off the mandrel as ast as it is ;.produced thereon by the'spiral winding arrangement described, 'itbeing understood that the rolls 41serve as feeding or drawing rolls as well as flattening rolls for the tube.

generally the.case that the paper being It will be understood that any suitable means (notshown) may be employed for tensioning the spools S and S so that the'threads therefrom will be drawn out under a proper degree of tension, which however for the for continuously cling yarns or filaments to reinforce the tube,

in a broader aspect these are optional and either the means for applying the lengthwise threads or the encircling threads, or both may be dispensed with should the product sought not require such reinforcing elements. Likewise while I show herein one spool carrier as rotatable in synchronism with the mandrel and the other spool carrier rotatable in the opposite directionfthisalso is to be understood-in a broader aspect as merel illustrative of spool carrier means, whic may be either stationary with respect to the mandrelor movable in either direction with reference thereto according to whether it is desired to have the-threads laid straight lengthwise of the tube or approximately straight crosswise, or at varying spiral angles. I therefore desire the present emboditrative and not restrictive, re erencebeing had to the appended claims rather than to the foregoing description to indicate the scope of the invention Having described my invention, what I claim as newand desire to secure by Letters Patent is: 3
